Fixed bug 4268 - Android_JNI_OpenAudioDevice function has error

alittle

where iscapture == 1

1.param set error

(*env)->CallStaticIntMethod(env, mAudioManagerClass, midCaptureOpen, sampleRate, audioBuffer16Bit, audioBufferStereo, desiredBufferFrames)

param:audioBuffer16Bit need change to captureBuffer16Bit

2.logic error

     1 .TH sdl2-config 1 "2012-02-20" "SDL 2.0"
     2 .SH NAME
     3 sdl2-config \- script to get information about the installed version of SDL
     4 .SH SYNOPSIS
     5 .B sdl2-config
     6 [ --prefix=
     7 .IR DIR ]
     8 [ --exec-prefix=
     9 .IR DIR ]
    10 [ --version ] [ --libs | --library-libs | --plugin-libs ] [ --cflags ]
    11 .SH DESCRIPTION
    12 .B sdl2-config
    13 is a tool that is used to configure and determine the compiler and linker
    14 flags that should be used to compile and link programs, libraries, and
    15 plugins that use SDL.  It is also used internally by the m4 macros that are
    16 included with SDL.
    17 .SH OPTIONS
    18 .TP
    19 .B --cflags
    20 Print the compiler flags that are necessary to compile a program or library
    21 that uses SDL.
    22 .TP
    23 .BI --exec-prefix= DIR
    24 If specified, use
    25 .I DIR
    26 instead of the installation exec prefix that SDL was build with when
    27 computing the output for the --cflags, --libs, --library-libs, and
    28 --plugin-libs options.  This option must be specified before any of the
    29 --cflags, --libs, --library-libs, and --plugin-libs options.
    30 .TP
    31 .B --libs
    32 Print the linker flags that are necessary to link a program that uses SDL.
    33 .TP
    34 .B --static-libs
    35 Print the linker flags that are necessary to statically link a program that uses SDL.
    36 .TP
    37 .B --library-libs
    38 Print the linker flags that are necessary to link a library that uses SDL.
    39 (This excludes any static objects required for linking, since these must be
    40 linked only by executable programs.)
    41 .TP
    42 .B --plugin-libs
    43 Print the linker flags that are necessary to link an SDL-using object that
    44 is to be accessed via
    45 .IR dlopen (3).
    46 This may include static objects with PIC symbol information.  This option
    47 should
    48 .B not
    49 be used for ordinary shared libraries or standalone applications.
    50 .TP
    51 .BI --prefix= DIR
    52 If specified, use PREFIX instead of the installation prefix that SDL was
    53 built with when computing the output for the --cflags, --libs,
    54 --library-libs, and --plugin-libs options.  This option is also used for
    55 the exec prefix if --exec-prefix was not specified.  This option must be
    56 specified before any of the --cflags, --libs, --library-libs, and
    57 --plugin-libs options.
    58 .TP
    59 .B --version
    60 Prints the currently installed version of SDL on standard output.
    61 .SH EXAMPLES
    62 .TP
    63 gcc -o main.o $(sdl2-config --cflags) main.c
    64 is how you might use
    65 .B sdl2-config
    66 to compile a C source file for an executable program.
    67 .TP
    68 gcc -o my_app $(sdl2-config --libs) main.o util.o
    69 is how you might use
    70 .B sdl2-config
    71 to link compiled objects into an executable program.
    72 .TP
    73 gcc -o libSDL_nifty-2.0.so.0.0.1 $(sdl --library-libs) read.o write.o munge.o
    74 is how you might use
    75 .B sdl2-config
    76 to link compiled objects into a shared library.
    77 .TP
    78 gcc -o libnifty_xmms.so $(sdl --plugin-libs) stream.o blit.o deinterlace.o
    79 is how you might use
    80 .B sdl2-config
    81 to link compiled objects into a plugin for use by another program.
